Seriously consider cashing everything out and putting it in guaranteed investments. Even a 1-3% money market savings account is better than losing another 10-20% this year. And no, the economy's NOT going to suddenly rebound and GAIN 20% without you noticing, so don't worry about missing out on the eventual upswing. You'll have time to get your money back into the market.

That's true, in fact, one of my portfolios is a clump-money market account. I should probably look into moving a bigger percentage into that fund. 10% of my retirement disappearing is not fun to think about. :( I don't want to buy a smaller yacht.
